Living
The most sustainable garment is one that already exists. That single sentence covers most of what matters here, but the comparison is worth walking through because fast fashion's real cost is spread across water, labour, landfill and animal materials in ways the price tag hides.
| Criterion | Fast fashion | Secondhand |
|---|---|---|
| Cost per wear | Low sticker price, short garment life, high cost per wear. | Low price and proven durability — items that survived a first owner tend to survive a second. |
| New resource use | Full water, dye and fibre footprint per item. | Near zero additional production impact. |
| Microfibres | New synthetics shed most heavily in early washes. | Older synthetics shed less; natural-fibre finds avoid the issue. |
| Labour | Speed-driven supply chains concentrate wage and safety abuses. | No new production labour involved. |
| Animal materials | Leather, wool and down are common and hard to trace. | Buying existing animal materials adds no new demand, though many people still choose to avoid them. |
